PERU -- PANTIACOLLA LODGE & SANDOVAL LAKE LODGE

BOLIVIA -- RIO HEATH LODGE

1998

by Paul Champlin

I am offering up my lowland bird list from 1998 activities in se Peru and Bolivia.  I visited 11 lodges and conducted extensive inventory work (>30days each) at three of them.  This list is from that inventory work and excludes any birds found while guiding tour groups.  The list may have some inconsistencies in some names but none will leave you scratching your heads saying "what species was he talking about?".  Here I will provide an overview of the lodges and the birding there.

LODGE DESCRIPTIONS

PANTIACOLLA LODGE:

I start with the best birding lodge in se Peru (yes I think it beats Amazonia, Explorers and TRC).  Three of us found nearly 550 species there in under 30 days with a one day high of 181 (even though we didn't try for daily highs).  It's a little-known lodge that goes by the name of Pantiacolla (www.pantiacolla.com).  One thing I found amazing was that the bird activity stayed constant throughout the day.  At all of the other lodges, the activity died at about 10 in the morning.  We almost always skipped lunch because of the high activity levels in the forest.

The lodge is placed right at the base of the Andean foothills, where the Rio Madre de Dios exits the Andes and enters the Manu lowlands.  The juxtaposition of this lodge is perfect for ultra high bird diversity with the lodge itself sitting on the edge of a small plateau at 450m elevation and among a series of plateaus at 425m, 500m and a ridge up to 1100m.  Within 5 minutes walk of the lodge you can be in solid bamboo, primary varzea, primary terre firme, secondary forests, island habitats or river edge.  With a little more work you can find other habitats on their extensive trail system that covers the 1000ha of land abutting Manu and can even mount an overnight trip up to the Pantiacolla Mountains (1000m+ elevation) where you can overlook the lowlands Manu Biosphere Reserve.

Here, in a low scrap of cloud forest we had several singing Black Tinimou and had an Orange-breasted Falcon from one of the local cliffs.  Great sunrise!!!  Best birds of our stay were the Tinimou, Falcon, Cinnamon Tyrant-manakin (several times), nearly all of the bamboo obligates (Peruvian Recurvebill, White-cheeked Tody-flycatcher etc.), Harpy Eagle (seen several times in the lodge clearing and ate one of the pet macaws within 10feet of the kitchen), A Long-tailed Potoo (nested at the lodge clearing for several years running and we found 3 or 4 others), River Tyrannulet (fairly common on the riverine islands near the lodge), blue Headed Macaw (4-6 coming to a clay lick nearly every day with 75+ Yellow-fronted Parrots ), and what is likely a new species of Antpitta (Barry Walker, Mark Robins, Bob Ridgely and other experts can't id the recordings of it to species).  A Tree Swallow we had there is one of the first seen in Peru.  The lodge itself plays host to a large and diverse flock of birds that you don't normally see at eye level.  Tanagers, antbirds, furnarids, and flycatchers feed in the 1-5m tall trees right in the lodge clearing as the flock passes through on its daily routine while hummingbirds are always there for a good look.  The Tanager flocks at this lodge BEAT those at ANY other lodge in size, see-ability, and diversity.  We found several cloud forest and foothill species spilling down into the lowlands.

Another thing about this lodge is that it's placed perfectly for a trip through the Andean highlands, cloud forests, foothills and lowlands.  If you want to see birds, you can easily top 650 or 700 species with this trip: Cuzco to Cock of the Rock Lodge (2 full days there); Cock of the Rock to Pantiacolla (3 full days there); Pantiacolla to Manu Wildlife Center (2 full days there).  Fly out to Cuzco.  It's about a 10day trip.  Spend the majority of time at Pantiacolla!

Having visited many other lodges and regions of the Peruvian lowlands, I have to say that the birding at Pantiacolla is the best BY FAR!  We visited in early September, October and again in December and it was GREAT each time.  I was told by someone who had been there in July that it was "magical" then too.  Several other birder/ornithologists have visited there since and have stated the same.  If you go to southern Peru, check out the cutting edge in birding quality.  The accommodations are pretty good too.  (I would suggest October, though Bob Ridgely went there last July an said it was GREAT!!!) NO BUG SPRAY NEEDED!!!

SANDOVAL LAKE LODGE:

This lodge is a good bet for lakeshore species.  The perimeter of the lake is about 9 kilometers but that size is at least doubled when you take into account the number of hectares of Mauritia Palm swamp.  Within this swamp, there exists an Agami Heron colony of about 60 nests.  This is unknown anywhere else.  If you want to see the colony you must make arrangements ahead of time to go in.  Inkanatura travel (www.inkanatura.com) does not bring most people to see it since they do NOT want to disturb the birds.  Dr. James Clements , my wife Tracey and I were the ones who went in to confirm the species identity of this colony and had about 40 adult Agamis on open branches as close as 10m.  There were about 150 if you include the young (unfortunately Jim had the only camera… a small point and shoot).  I spent 5 months at this lodge as co administrator with my wife.  We tallied a little over 400 species with highlights: Harpy Eagle (5 or 6 during our stay at the lodge), the Agami colony, Great Jacamar (fairly common if you know the song), Black-banded Owl, Cinnamon Attila, Point-tailed Palm Creeper (common), Red-shouldered Parrotlet and Amazonian Antpitta.  The diversity and forest quality is not spectacular but for a less expensive trip to the rainforest, it's great.  There's a group of 11 or so Giant Otters on the lake too so that's a great bonus.  The lodge is like a hotel… no BETTER.  It's about 15 kilometers from Pto.  Maldonado with a 3kilometer, birder friendly trail into the lake.  The lodge is right on the lake.

RIO HEATH LODGE:

The third lodge I would like to mention is the Rio Heath Lodge, just over the Bolivian border.  It's an extension trip to Sandoval.  From Sandoval you head down to the Bolivian border and up the Rio Heath, which makes up the border.  They have a special arrangement with the border folks that you can stay IN Bolivia where the lodge is, without leaving Peru (on paper).  The diversity at this lodge is midway between Sandoval and Pantiacolla with the larger birds and mammals being more common than either and quite unwary.  It's sandwiched by 2 reserves, each 1.5 million hectares.  This makes the animals unwary and easy to see.  Another benefit is that within 45minutes (fast walk) of the lodge is an extensive brushy savanna (more grassy in the middle).  This area increases the diversity for the lodge by quite a bit and makes it easy to see the birds that stay in this brushy habitat.  I have recordings and photos of a bird which is likely a new species of flycatcher OR is the new species (Tolmomyias trailori) from NORTHERN PERU!!!  There are many EXCELLENT birds to be seen at this lodge including Pale-bellied Mourner (not known from this region until now), Great Jacamar (common), Maguari Stork, Plain Softtail (fairly common), both local Formicivora antbirds, Undulated Antshrike, Crested Eagle (in same spot for 4 months), all of the normal savanna birds, Buff-necked Ibis, Long-tailed Potoo (at lodge clearing as well as Great Potoo on nest) AND the SAME unidentified Antpitta from Pantiacolla!!!  As with Pantiacolla, this lodge constitutes the CUTTING EDGE of birding with undiscovered species certainly on site.

This lodge is GREAT (!!!!) for CATS!!!!  Only 2 tour groups had visited by the time we arrived at the just finished lodge.  The groups had already seen Ocelot and Tracey and I got charged by a mother Puma (Mountain Lion) protecting her young.  That's a story in itself.  While we were there we identified at least 3 different Jaguar territory borders WITHIN 200m of the lodge (they converged at the lodge).  We often found large cat tracks in our fuutprints as we returned to the lodge from a day of birding.  The only other group to visit while we were there saw and photographed a pregnant female Jaguar on a riverbank log as they headed up to the parrot/macaw lick 5 minutes up stream.  It stayed for 10 minutes while they got to within 10 meters.  There are at least 5 mammal clay licks and 1 macaw clay lick within 1km of the lodge.

The macaw lick is FANTASTIC with Peach-fronted Parakeet, Red-shouldered Macaw (A.  nobilis), Orange-winged Parrot, up to 100 Red and Green Macaws and the regular host of other parrots AND GREAT LIGHTING.  It's small, compact and low to the river.  The bank is only about 6 meters tall and the river is only 50m wide or less.  We noticed on our several short visits and one 45 day stay that this clay lick is quite active throughout the entire year.

LIST OF BIRDS AT SANDOVAL LAKE LODGE & PANTIACOLLA LODGE, DPTO. MADRE DE DIOS, SE PERU AND RIO HEATH LODGE, DPTO. LA PAZ, BOLIVIA

By Paul Tracey Crowningshield

Visit dates by P&T Champlin

This list of 600+ species documents the avian communities of three lodges in the Rio Madre de Dios drainage.
 

SANDOVAL LAKE: 15km down the Madre de Dios from Pto. Maldonado; It is mostly second growth and primarily terre firme. 200m elevation.  Includes a large lake and palm swamp. 389 species.  18 March 1998 until 11 August 1998.

RIO HEATH: On the Bolivian side of the Peru/Bol. border; this lodge has good representation of lowland forest types. 175m elevation.  Lack of access to the Peruvian side of the river eliminates most Bamboo birds. This is made up for by savannah species. 432 species.  27 October 1998 until 8 December 1998.

PANTIACOLLA: 2hrs down the Alto Madre de Dios from Atalaya; a region with one of the highest habitat diversities. 400m - 1000m elevation.  Elevational plateaus of various habitats surround the lodge. 516 species by several observers. The best birding lodge ever visited by the authors.  10 September - 2 October 1998, plus 10 later days.
